WebBusbar Protection Busbar protection schemes must be tested to confirm high speed operation, ensure absolute stability for external faults, and to give complete discrimination between the different protection zones. From: Transmission and Distribution Electrical Engineering (Fourth Edition), 2012 View all Topics Add to Mendeley About this page WebMay 18, 2024 · Summation Summation transformers are employed for comparing the relaying values derived from the output in the three phases of the primary section. This is performed by transforming the three-phase values into the single-phase quantity. The line current transformers are attached to the primary section of the auxiliary current transformer.
